Bit Perfect Audio from Linux - Page 21

post #301 of 303

Hi bcschmerker4®,

 

Whether the interface is balanced (IEC 60958 Type I using XLR) or not (IEC 60958 Type II using RCA/coax) is of no importance to the symptoms. Both interfaces carry computer generated SPDIF-signals with all problems related to it. Those subtle problems in sound quality are inherent to the SPDIF-signal, and exist even when there is proper signal transfer without coarse issues like grounding loops, signal decay and/or dropped packets.

 

The latter problems could benefit from dedicated sound hardware inside the PC coupled to balanced connections. On the other hand, if you experience those issues at your home setup, something else is wrong. They are intended for professional use where long distances between devices are required and the prevention of electrical problems (in the rest of the delivery chain) is more important than sound quality. That's also the reason that currently not a single professional audio device exists which aims at bit-perfectness in the whole chain.

 

Regards,

Ronald

Thanks, @ronalde, for the additional details on the problem.  As of August 2014, the Creative Laboratories® SB0350 PCI 2.2 card and SB0250 I/O Drive are still functional in my custom LinUX box; I'm still debating a potential re-build around an Intel® Core Processor™ i5-3500 Series APU (FCLGA 1155), ASRock® Z68 Pro-3M, and up to four new Western Digital® Caviar Red® hard drives, as JACK™ doesn't want to fly at all speeds on the current Advanced Micro Devices® Athlon 64® X2 5600+ (running at 2.9 GHz) and 780G/SB700 chipset.

Jack is middleware aimed at (semi-)professional usage and aims for troublefree and "realtime" routing of multiple audio streams, like pulseaudio is middleware targeted towards desktop users providing them a seamless plug-n-play experience.

 

Those layers settle for one single fixed sample rate and bit depth for all streams by providing automagic resampling, bit depth conversion and/or leveling. In other words bit-imperfectness is their raison-d'être.
